Abstract The paper presents the possibility of using data mining tools — artificial neural networks in prediction hydrometer reading after 24 h order to limit duration test 4 h. authors analysed a database 693 granulometric composition analysis results genetically different soils with use radial basis function network (RBF) and multilayer perceptron (MLP). calculations performed showed that it ...

The shallow foundations that often characterizes multi-span masonry arch bridges are highly vulnerable to the soil settlements typically induced by riverbed scouring. Consequently, monitoring of scouring effects is paramount importance ensure safe operation these river bridges. Within a recent collaboration between Politecnico di Milano and Regione Lombardia, bridge has been selected exemplify ...

An algorithm based on a support vector machine (SVM) is proposed for hydrometeor classification. The training phase is driven by the output of a fuzzy logic hydrometeor classification algorithm, i.e., the most popular approach for hydrometer classification algorithms used for ground-based weather radar. The performance of SVM is evaluated by resorting to a weather scenario, generated by a weath...

Methods to predict soil hydraulic properties frequently require information on the particle size distribution (PSD). The objectives of this study were to investigate various protocols for rapidly measuring PSD using the laser diffraction technique, compare the obtained PSD with those determined using the traditional hydrometer-and-sieves method (HSM), and assess the accuracy of soil hydraulic p...

INTRODUCTION Embalming is the through disinfection and art of preserving bodies after death using chemical substances. It keeps a body life like in appearance during the time it lies in a state prior to funeral. OBJECTIVE This study was undertaken to investigate the effectiveness of Raksi in sacrificed rats in arresting postmortem changes and establishing scientific fact whether Raksi can be ...

Digging by gophers disturbs near-surface soils, deposits sediment in mounds and “eskers” in non-uniform surface patterns, and affects surface penetrability of soils at alpine treeline. Soil samples were collected and soil compaction was measured at three sites in the Culebra Range of the Sangre de Cristo Mountains in southern Colorado, to determine the effects of gophers on surface compaction a...

Classification of hydrometeors has a wide variety of applications such as validation of cloud microphysical models, choice of algorithm for precipitation estimation and evaluation of assumptions made in the precipitation retrieval processes as well as validation of space borne observations. Dual-polarization radar measurements are sensitive to hydrometeors properties such as size, shape, phase ...
